LEVI S. REYNOLDS, OF INDIANAPOLIS, INDIANA.

BRAIN-DUSTER.

Specification of Letters Patent No. 9,819, dated June 28, 1853.

To all whom it may concern Be it known that I, LEVI S. REYNOLDS, of Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Bran-Dusters, denominated the Indiana Bran-Duster and I do hereby declare that the following is a full, clear, and exact descrlption of the same, reference being had to the annexed drawings, forming part of this specification, in which Figure 1 is a side elevation of the machine with casing and bolting cloth removed. Fig. 2 is a side elevation of the same, having the bolting cloth in position and one side of the casing removed. Fig. 3 is a vertical section through the axis of the shaft, and parallel to the side of the machine.

Similar letters of reference in the several figures denote the same part of the machine.

My invention relates to the employment of an additional scourer, through which the finer grades of offal are passed after separation from the coarser, in order that they may be subjected to the requisite degree of friction for producing the desired effect, without involving the necessity of the coarse offal undergoing the same process, and consequently becoming injured by cutting; also, to the arrangement of the bolting cloths so as to be capable of a vertical vibratory motion for preventing the clogging of the cloth; and further, to an arrangement by which a current of air is passed through the bolting cloths, for throwing the flour and bran against them, and effecting the separation in a superior manner.

In the drawings AA are the posts of the frame, and a, a cross piece holding the vertical shaft 6, which rests in the step e and is revolved by a band passed over the pulley B. Upon the upper portion of the shaft 6 is fastened the conical scourer c (seen in Fig. 3) which is covered with the projections 2 formed by puncturing the metallic face of the scourer. Over the conical scourer c, is placed the cap d, having the projections a: upon its under surface, formed in a similar manner to the project-ions i/ on the cone 0; the distance of the cap (Z from the conical scourer 0 is adjustable by screws or register so that the cone may revolve any required distance from the cap. Below the cone 0 and connected with its cap (Z is the funnel 6 leading to the opening f, which communicates with the lower scouring apparatus, consisting of the two horizontal plates 9 and h, attached to and movable with the shaft b. The former of these plates is perforated like the cone 0 and cap (Z, forming the projections to on its under surface, and the latter is armed with the spikes or heaters 11 placed either in regular or promiscuous order, and nearly equal in length to the dlstance between the plates. These two plates always preserving the same rela' tive positions with each other and revolving together. Beneath the plate It is the cylindrical air chamber 2' secured to the shaft Z2 and movable with it; in its surface are the perforations 0, and radiating from it the wings or fans j. The lower base of this cylinder is also furnished with openings, which when the cylinder is in motion admit a cur rent of air, which passing out the openings 0 in the surface of the cylinder and between the wings j is thrown ofi by the latter against the bolting cloths, with an effect that will hereafter be described. Surround ing the lower scouring plates g and h, and the air cylinder i are the bolting cloths t secured to the frames 1 which are inserted between the posts A; these frames r restupon the springs m, and are capable of a vertical motion between the posts A, which is produced through the pin Z by means of the hammer a attached to the spring q. EX- terior to the frames r are the casings C, leaving the spaces 8 between them and the bolting cloths 2f.

The operation of my improved bran duster, the several parts of which are described above, is as follows: Before being submitted to the action of this machine the finer grades of oifal are separated from the coarser by a shoe, and then enter the upper scourer by the hopper H. After being acted upon by the projections 90 and y they fall into the funnel e and pass by the opening f to the second or lower scourer, consisting of the plates 9 and h, when the fine offal meets the coarser grades which enter the machine through the opening f. The bran and flour after being subjected to the action of the heaters 41 and projections to gradually work their way to the verge of the plate It and fall over it into the strong current of air above described. This centrifugal current throws the bran and flour against the bolting cloths t, causing the latter to be carried through them into the spaces 8 between the bolting cloths and casings G, from which it falls through the openings F into the proper receptacle, while the bran perfectly cleaned falls through the openings 79. The shaking of the machine, caused by the revolution of the shaft 6 and parts connected with it or by any convenient and suitable device, or in any effective manner preferred produces a vibration of the spring 9, causing the ham-1 mer n attached to it to strike the pin- Z, producing in the frames 7* a vertical vibratory motion by reason of the springs m upon which they rest; this motion is kept up during the operation of the machine, and effectually cleans the bolting cloths and prevents them from becoming clogged with the fine flour. But one hammer n and adjacent parts is shown in the drawing, though in practice one is required for each of the frames 7".

This machme does not require to be run at as great a degree of speed as is usual for bran dusters; which excessive velocity employed in other machines has a tendency to throw the offal away from the heaters, and impair the operation. The manner in which the current of air is produced in this machine is far more effective than the methods employed in other machines, as it prevents What I claim as my invention and desirev to secure by Letters Patent, is

, The employment of the conical roughened metallic scourer a, in combination with the double disk ruuber g h the disks and pins of which always preserve the same relative positions being arranged and operated in the manner and for the purpose set forth.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.
